ANTIRATTLING DEVICE FOR WINDOWS Filed Jan. 3, 1936 INVEN OR WITNESS ATTORNEY Patented Oct. 12, 1937 UNITED s'rA ATENT OFFECE 1 Claim.

This invention relates to anti-rattling devices and has for an object to provide an extremely simple and inexpensive anti-rattling device which will obviate the necessity for window weights, sash cords, and rollers and will hold the window in any adjusted position.

A further object of the invention is to provide a device of this character which can be easily installed without skilled labor and at minimum expense and will require only a simple diagonally extending groove to be out in the sash and a staple for mounting the device in the groove.

A further object is to provide a device of this character which will not easily get out of order when once installed and which will be inexpensive to replace should it become damaged under severe conditions of service.

With the above and other objects in View the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a vertical sectional view through a window with portions broken away and showing the upper and lower sashes equipped with anti-rattling devices constructed in accordance with the invention.

Figure 2 is a diagonal sectional view through the window style taken on the line 2-2 of Figure 1 with the leaf spring anti-rattling device in place.

Figure 3 is a perspective view of the notched leaf spring comprising the anti-rattling device.

Figure 4 is an end elevation of a sash having a diagonal groove cut therein to receive the leaf spring shown in Figure 3.

Figure 5 is a longitudinal sectional view through a sash equipped with a weather strip and showing a modified form of anti-rattling de- 4 vice applied thereto.

Figure 6 is a perspective view of the anti-rattling device shown in Figure 5;

Referring now to the drawing in which like characters of reference designate similar parts in the various views, it) indicates the upper and lower sashes which may be adjusted to any open position in grooves it formed by a parting strip l2 in the window casing l3.

The anti-rattling devices forming the subject matter of this invention consists of a leaf spring M which is adapted to be mounted edgewise in a slot l5 cut diagonally across the edge of the sash. The ends [6 and I! of the spring are curved, as shown, outside of the faces l8 and IQ of the sash and overlie recesses 20 and 26' formed in the faces of the sash. A staple 2| anchors the spring to the sash and has the bight engaged in a notch 22 in the edge of the spring to hold the spring against endwise movement in the staple.

In operation the upper end It of the spring 10 will frictionally engage the parting strip. l2 while the lower end will frictionally engage the vertical sash retaining strip 23 of the window casing and by virtue of the resiliency of the spring the sash may be adjusted to any desired open position 15 and will remain in this adjusted position.

To adapt the device to windows equipped with weather strips 24, as shown in Figure 5, the leaf spring 26 is disposed edgewise in a diagonal slot 2? cut in the side edge of the sash and the upper 20 and lower ends 28 and 29 of the spring are bent back to extend parallel with each other on the same side of the spring and overlie respective recesses 30 and 3| formed in one side face of the sash and in the center of the sash at the part- 25 ing strip, respectively. A staple 32 anchors the spring to the sash, the bight of the staple being engaged in a notch 33 in the spring to hold the spring against endwise movement in the staple.

The modified form of anti-rattler shown in 30 Figure 6 is disposed in pairs on each sash, as shown in Figure 5, so that the bent ends 29 abut against the weather strip 24 while the free ends 28 press against the customary vertical guide strips of the window casing. By use of the modi-. fled form of the invention cutting of the weather strip is avoided.

From the above description it is though that the construction and operation of the invention will be fully understood Without further explanation.

What is claimed is:

An anti-rattling device for window sashes comprising a straight leaf spring having a notch in its edge and adapted to be imbedded in an oblique slot in the edge of a sash and having the ends curved in opposite directions and adapted to extend along the inner and outer surfaces of the sash for engagement with guide strips of the winr dew frame, and a staple adapted to anchor the leaf spring to the sash and having the bight engaged in the notch in the edge of the leaf spring, the legs of the staple straddling the leaf spring.
